Map point to DMS

Udaya_BhaskerCheerala — Sat, 26 Jan 2013 15:16:16 GMT

Dear All,

I would like to conver map coordinates (-103.5234,48.56781) to DMS(Degrees Minutes Sec). My map is in WKI:4269.

Can anybody help me how to do it in JSAPI.

Thanks,
Uday

I've written code to perform the conversion the other way (DMS to DD).

I did a search and found a lot of samples for doing the conversion from DD to DMS. This one looks promising.

Hi,

Here is my code to show DMS coordinates on Map Screen using ArcGIS API Javascript

// Coordinates on Screen
  map.on("load", function() {
   //after map loads, connect to listen to mouse move & drag events
   map.on("mouse-move", showCoordinates);
   map.on("mouse-drag", showCoordinates);
  });

  function deg_to_dms (deg) {
    var d = Math.floor (deg);
    var minfloat = (deg-d)*60;
    var m = Math.floor(minfloat);
    var secfloat = (minfloat-m)*60;
    var s = Math.round(secfloat);
    
    if (s==60) {
  m++;
  s=0;
    }
    if (m==60) {
  d++;
  m=0;
    }
    return ("" + d + '&deg;' + m + '\'' + s + '" ');
  }

  function showCoordinates(evt) {

   //the map is in web mercator but display coordinates in geographic (lat, long)
   var mp = webMercatorUtils.webMercatorToGeographic(evt.mapPoint);
  //convert DD to DMS
     var lat = deg_to_dms(mp.y);
   var lon = deg_to_dms(mp.x);
   //display mouse coordinates
   dom.byId("coordinate").innerHTML = lat + 'N' + ", " + lon + 'E';
  }
